Hi, writing a Java TCP socket program consisting of a client and a server. I have finished the requirements for the client, but need help with the server portion. I need to modify the code at the bottom so that the Local Server S (localhost):

1. listens for and accepts the connection from C (the client) on port 11211
2. receives and prints the message WEB SERVER= followed by Ws name sent by C
3. prints the message IP ADDRESS= followed by Ws IP address
4. prints the message SERVER START= followed by Ss local system time ST1
5. uses the class HttpURLConnection to connect to the web server W on port 443
6. receives Ws page from the web server W
7. prints the message SERVER END= followed by Ss local system time ST2
8. prints the message SERVER DELAY= followed by the value of ST=ST2-ST1 in milliseconds
9. sends to C the page received from the web server W
10. sends to C the value of ST

Additionally, the code should not have any threads, and System.exit() cannot be used. Here is the code that needs to be modified:

import java.io.*; import java.net.*; class TCPKRServer { public static void main(String argv[]) throws Exception { String clientSentence; String capitalizedSentence; ServerSocket welcomeSocket = new ServerSocket(6789); while(true) { Socket connectionSocket = welcomeSocket.accept(); BufferedReader inFromClient = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream())); DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream()); clientSentence = inFromClient.readLine(); capitalizedSentence = clientSentence.toUpperCase() + ' '; outToClient.writeBytes(capitalizedSentence); } } }
